Plugin namespace helpers

To avoid symbol conflicts when employing static linking, it is a good idea to put everything into a private namespace.

The CS_PLUGIN_NAMESPACE_BEGIN and CS_PLUGIN_NAMESPACE_END macros help with that by putting the plugin namespace into a sub-namespace for plugins.

Use like:

 #include <...>

 CS_IMPLEMENT_PLUGIN

 CS_PLUGIN_NAMESPACE_BEGIN(MyPlugin)
 {
   ...
   MyClass::MyClass (...) { ... }
   ...
 }
 CS_PLUGIN_NAMESPACE_END(MyPlugin)

To refer to members of the namespace (e.g. for template specializations, use CS_PLUGIN_NAMESPACE_NAME.

#define CS_PLUGIN_NAMESPACE_BEGIN(name)   namespace CS_NAMESPACE_PACKAGE_NAME { namespace Plugin { namespace name
#define CS_PLUGIN_NAMESPACE_END(name)   } }
#define CS_PLUGIN_NAMESPACE_NAME(name)   CS_NAMESPACE_PACKAGE_NAME::Plugin::name

Detailed Description

This file should be #included before any other Crystal Space header files.

It sets up a compilation environment which smooths over differences between platforms, allowing the same code to compile cleanly over a variety of operating systems and build tools. It also provides a number of utility macros useful to projects utilizing Crystal Space and to the Crystal Space code itself.

Definition at line 894 of file cssysdef.h.

#define CS_ASSERT (   x)    (void)0

Assertion.

If expr is false, a message containing the failing expression as well as a call stack is printed to stderr and a debug break is performed

Remarks:

 {
   int newStuff;

  decl 
)    decl CS_ATTRIBUTE_DEPRECATED_MSG(msg)

A variant of CS_DEPRECATED_VAR that also emits the message msg on compilers that support it.

Definition at line 270 of file cssysdef.h.

#define CS_DEPRECATED_VAR_MSG (   msg,
  decl 
)    CS_DEPRECATED_VAR(decl)

Definition at line 270 of file cssysdef.h.

Disable deprecation warnings in following statements.

Always try to actually fix the root cause of a deprecation warning before employing this. Should be followed by CS_DEPRECATION_WARNINGS_ENABLE after the statements that caused the warnings. Suitable for use in macros.

Definition at line 1268 of file cssysdef.h.

Enable deprecation warnings in following statements.

Suitable for use in macros.

Definition at line 1269 of file cssysdef.h.

#define CS_FUNCTION_NAME   __PRETTY_FUNCTION__

Macro that resolves to a compiler-specific variable or string that contains the name of the current function.

Definition at line 782 of file cssysdef.h.

#define CS_HEADER_GLOBAL (   X,
 
)    CS_HEADER_GLOBAL_COMPOSE(X,Y)

The CS_HEADER_GLOBAL() macro composes a pathname from two components and wraps the path in `<' and `>'.

This macro is useful in cases where one does not have the option of augmenting the preprocessor's header search path, even though the include path for some header file may vary from platform to platform. For instance, on many platforms OpenGL headers are in a `GL' directory, whereas on other platforms they are in an `OpenGL' directory. As an example, in the first case, the platform might define the preprocessor macro GLPATH with the value `GL', and in the second case GLPATH would be given the value `OpenGL'. To actually include an OpenGL header, such as gl.h, the following code would be used:

 #include CS_HEADER_GLOBAL(GLPATH,gl.h)
 

Definition at line 342 of file cssysdef.h.

#define CS_HEADER_LOCAL (   X,
 
)    CS_HEADER_LOCAL_COMPOSE1(X,Y)

The CS_HEADER_LOCAL() macro composes a pathname from two components and wraps the path in double-quotes.

This macro is useful in cases where one does not have the option of augmenting the preprocessor's header search path, even though the include path for some header file may vary from platform to platform. For example, assuming that the preprocessor macro UTILPATH is defined with some platform-specific value, to actually include a header, such as util.h, the following code would be used:

 #include CS_HEADER_LOCAL(UTILPATH,util.h)
 

Definition at line 357 of file cssysdef.h.

#define CS_IMPLEMENT_IMPLICIT_PTR_CAST (   classname)
Value:
inline static classname* _CS_IMPLICITPTRCAST_NAME (classname* ptr) \
  { \
    return ptr;\
  }

Implements a static member function for a class which can be used to perform implicit pointer casts.

Parameters:
classnameName of the class that the macro is being used in.
Remarks:
This macro is intended to support typecasting within macros, allowing the compiler to provide a more descriptive error message. Use CS_IMPLEMENT_IMPLICIT_PTR_CAST() in the declaration of the class and CS_IMPLICIT_PTR_CAST() in the macro declaration.
Example:
 struct iObjectRegistry : public iBase
 {
   // Allow implicit casts through static function.
   CS_IMPLEMENT_IMPLICIT_PTR_CAST(iObjectRegistry);
   ...
 }

 #define CS_QUERY_REGISTRY_TAG(Reg, Tag) \
  csPtr<iBase> (CS_IMPLICIT_PTR_CAST(iObjectRegistry, Reg)->Get (Tag))

Definition at line 1174 of file cssysdef.h.

#define CS_IMPLICIT_PTR_CAST (   classname,
  ptr 
)    (classname::_CS_IMPLICITPTRCAST_NAME(ptr))

Perform a compiler implicit cast of a pointer to another pointer type using a static member function declared with the CS_IMPLEMENT_IMPLICIT_PTR_CAST macro.

Parameters:
classnameName of the class to convert to
ptrPointer to be convereted into
See also:
CS_IMPLEMENT_IMPLICIT_PTR_CAST

Definition at line 1188 of file cssysdef.h.

This is defined when the project was compiled without support for exceptions.

Definition at line 284 of file cssysdef.h.

#define CS_STRING_TO_WIDE (   x)    CS_STRING_TO_WIDE_(x)

Convert a string to a wide string.

Also works in macros.

 void bar (const wchar_t* baz);
 #define FOO(x) bar (CS_STRING_TO_WIDE (#x));

Definition at line 1212 of file cssysdef.h.

#define CS_VA_COPY (   dest,
  src 
)    __va_copy(dest, src)

Copies the state of a va_list value.

Definition at line 1198 of file cssysdef.h.
